plants have two modes of nutrition, autotrophic and heterotrophic mode. Based on the method of obtaining food hydrotropic are further classified into -
parasitic plant
saprophytes
symbiotic plant
insectivorous plant
Lichen are symbiotic organism, in which an alga and a fungus live together and derive nutrients from each other. The alga is green and autotrophs. It makes food for both by photosynthesis. The fungus provide shelter, water and mineral to the alga.
the Hardy lichens are useful bioindicator for air pollution, especially sulfer dioxide pollution, since they derive their water and essential nutrients mainly from the atmosphere rather than from the soil.
